Abstract: A display device includes: a display layer; a sensor layer on the display layer; a sensor driving part to provide a transmission signal to the sensor layer; and a display driving part to drive the display layer. The display layer includes: a plurality of pixels; first scan lines electrically connected to a first group of pixels; second scan lines electrically connected to a second group of pixels; and data lines electrically connected to the plurality of pixels. The display driving part is to drive the first scan lines, the second scan lines, and the data lines, and to alternately provide a pixel data signal and a compensation signal to data lines corresponding to the first group of pixels and data lines corresponding to the second group of pixels, the compensation signal being a signal that is complementary to at least one of the pixel data signal or the transmission signal.
